A stronger economy, rising consumer confidence and cheap gasoline will likely have Americans traveling in big numbers this Independence Day.

Travel agency and car lobbying group AAA estimates 41.9 million people will travel 50 miles or more from home during the holiday weekend, up 0.7 percent from last year and the most since 2007, right before the recession.

As usual, the vast majority of travelers will be using their cars: about 85 percent. Gas currently costs $2.78 a gallon, down 88 cents from the same time last year. That means a family driving 200 miles on highways will save about $7.30 for their holiday gas this year.
